Introduction

Cloud computing has become a game-changer in today’s digital era, and AWS Cloud (Amazon Web Services) is the leader in the field. It is an on-demand cloud computing platform that provides scalable, reliable, and cost-effective solutions to businesses and developers.

Previously, companies had to maintain their own servers and infrastructure, which was very expensive and complex, and took a lot of time. It has completely changed this, in which you can use only as much computing power as you need without any heavy investment, and you have to pay only as much money as you can use.

The work of AWS is simplified:

1.On-Demand Computing Power – You can lease as much computing power as you want.
2.Pay-as-you-go Model – Just pay as much as you use.
